Abstract

A reverse micelle method has been developed to coat a transparent nanocrystalline titanium dioxide thin film on glass.  This method involves Triton X-100 (surfactant), hexanol (co-surfactant), cyclohexane (continuous phase), titanium isopropoxide and water.  A uniform thin film is obtained by dip coating the glass in the reverse micelle solution.  After drying and calcination in air, a multifunctional thin film of nanocrystalline TiO2 is formed.  The coated glass exhibits self-cleaning, antibacterial, and photocatalytic properties.
